Can you record WhatsApp calls?

No, not properly. WhatsApp has no built-in call recording for voice or video calls, and it isn’t coming, the app is built around end-to-end encryption. The workarounds are screen recording (patchy, and on iPhone the call audio usually isn’t captured) or recording on a second device (works, sounds terrible). If you need WhatsApp calls recorded for business, the honest answer is: change the channel, not the app.

I’ll walk through what’s technically possible, the legal position, and then the part that regulated firms keep learning the expensive way.

Why doesn’t WhatsApp have call recording?

Because recording is the opposite of the product. WhatsApp’s pitch is private, end-to-end encrypted communication, Meta’s servers can’t listen to your calls, and the app offers no hook for anyone else to either. There’s no record button, no API for recording, and no supported integration that captures calls. Any recording therefore has to happen outside WhatsApp, at the device level, which is where the workarounds come in.

Can you screen-record a WhatsApp call?

Sometimes, and the platforms behave differently:

On Android, the built-in screen recorder on many modern handsets can capture a WhatsApp call, including audio, on some devices. Whether internal call audio gets captured varies by manufacturer and Android version, plenty of devices block internal audio capture for VoIP calls, leaving you with video and your own voice only. Some third-party recorder apps claim WhatsApp (VoIP) support on certain handsets, with the same reliability caveats I covered in How to record phone calls on Android: it works until an update quietly breaks it.

On iPhone, the news is worse. iOS screen recording generally does not capture the call audio of a WhatsApp call, you get silent video. (Note that iOS 18’s built-in call recorder only works for normal phone calls, not WhatsApp, see How to record phone calls on iPhone.) Enabling the microphone in screen recording captures your voice through the mic but typically not the other party. The workaround people land on is putting the call on speaker and recording the room, either with the Voice Memos app or a second device.

The second-device method works everywhere and is exactly as clunky as it sounds: speakerphone on, another phone recording next to it, audio quality dictated by your kitchen acoustics.

If you test any of these, do a trial run with a friendly contact first and check both sides are actually audible. The most common outcome of WhatsApp-recording workarounds is discovering afterwards that half the conversation isn’t there.

Is it legal to record a WhatsApp call in the UK?

The law doesn’t care that it’s WhatsApp. A call is a call:

• Private individuals can record their own conversations for personal use without telling the other party
• Businesses need a lawful basis under UK GDPR and must inform participants that the call is recorded
• Sharing or publishing a recording moves you into different, riskier territory regardless of how it was made

WhatsApp’s encryption changes the engineering, not the law. The one practical wrinkle: since none of the workarounds announce themselves, a business recording a WhatsApp call has to remember to give the notice verbally. The full legal picture, RIPA, UK GDPR, admissibility in court, is in Is it legal to record a phone call in the UK?

Why do regulators keep punishing firms over WhatsApp?

Here’s where this stops being a how-to question and becomes a governance one. If your firm has recording or record-keeping obligations, the fact that WhatsApp calls and chats can’t be reliably captured is precisely the problem.

The enforcement record is real, not hypothetical:

• In Great Britain, Ofgem fined Morgan Stanley £5.41 million in 2023 for failing to record and retain WhatsApp communications by its wholesale energy traders on private phones, the first fine of its kind in GB under the requirements to record and retain electronic trading communications. Notably, Morgan Stanley had a policy banning WhatsApp for trading communications, the failure was not enforcing it.
• In the US, the SEC and CFTC have imposed well over $2 billion in penalties on major banks since 2021 for “off-channel” communications, business conducted over WhatsApp, Signal and personal devices where it couldn’t be captured or supervised.
• The FCA has so far preferred supervision to headline fines, but it has surveyed firms on encrypted messaging use, found scores of internal policy breaches (a large share from senior staff), and its recording rules in SYSC 10A apply to in-scope communications on any channel. There is no WhatsApp carve-out, and no reason to assume the supervisory patience is permanent.

The pattern in every case is the same: business communications happened on a channel the firm couldn’t record, and the regulator treated that as the firm’s failure. “The app doesn’t support recording” is not a defence, it’s the charge sheet.

What should regulated firms do instead?

Two things, and they only work together:

1. A policy with teeth. In-scope business conversations happen on approved, recorded channels, full stop. WhatsApp can still exist for “running late, call you in five”, but the moment a conversation becomes substantive, it moves to a recorded line. Morgan Stanley’s fine shows a policy alone isn’t enough, it has to be enforced and evidenced.

2. An approved channel that’s actually easy to use. Policies get bypassed when the compliant route is clunky. This is where network-level mobile recording earns its keep: staff carry one phone with a business SIM, they dial normally from the native dialler, and every call and SMS on that number is recorded automatically on the network. Nothing to launch, nothing to press, nothing to forget, and nothing an individual can quietly bypass. The line of least resistance becomes the compliant one.

That’s what ONSIM provides, mobile call and SMS recording for general business use, and mobile compliance recording for FCA-regulated deployments, with configurable retention and integration into compliance archives. If you also want those recorded calls transcribed and searchable, that’s covered in AI call transcription for business.

The honest summary

• Can you record WhatsApp calls? Not natively, ever. Workarounds exist, they’re unreliable, and on iPhone they mostly don’t capture call audio.
• Personal use? If a workaround suits you, UK law allows recording your own calls, just don’t share the recording casually.
• Business use? If a call is worth recording, it’s worth having on a channel that records properly. Fighting WhatsApp with screen recorders is solving the wrong problem.
• Regulated firm? The enforcement history is unambiguous. Get in-scope conversations off WhatsApp and onto a recorded channel before a regulator does the maths for you.
